Cloud computing involves storing and accessing data and programs over the Internet instead of a local computer's hard drive. It has a front-end and back-end connected through a network, usually the Internet. The back-end consists of data centers containing distributed servers that act as a single system. There are three main types of cloud services: Infrastructure as a Service (IaaS) provides basic storage and networking; Platform as a Service (PaaS) provides development tools; and Software as a Service (SaaS) provides complete applications that users access through a web browser. Cloud computing offers advantages like lower costs, improved performance and collaboration capabilities, but also risks like dependence on constant network access and potential security issues.

1. CLOUD COMPUTING
A Seminar On

2. Introduction
 Cloud Computing is use of remote servers on the
internet to store, manage and process data rather
than a local server on your personal computer.

3. Introduction
 Cloud Computing is distributed computing on internet or
delivery of computing service over the internet.
 Cloud Computing is a combination of software and
hardware based computer resource delivered as network
services.
Some well known Cloud providers are :
 Amazon Web Services
 Microsoft Azure
 Google Cloud Platform
 IBM Cloud

4. Cloud Computing Architecture
 Cloud Computing architecture comprises of many cloud
components, which are loosely coupled.
 We can broadly divide the cloud architecture into two
parts:
1. Front End
2. Back End
 Each of the ends is connected through a network, usually
Internet.

5. Cloud Computing Architecture

6. Cloud Components
Cloud has three components :
I. Client Computers
II. Distributed Servers
III. Data Centers

7. Cloud Components
Client Computers:
Client Computers are devices that the end user
interact with cloud.
Client Computers are of three types:
1. Mobile
2.Thick
3.Thin
Datacenters :
It is collection of servers where application is placed and
is accessed via internet.
Distributed Servers :
Often servers are in geographically different places, but
servers act as if they are working next to each other.

8. Types Of Cloud Models

9. Deployment Model
 Deployment models defines the type of access to
the cloud.
Cloud can have any of the four type of access :
I. Public
II. Private
III. Hybrid
IV. Community

10. Deployment Models

11. Service Model
 Service Models are the reference model on which
Cloud Computing is based.
Service Models are divided in three categories :
I. SaaS (Software as a Service)
II. PaaS (Platform as a Service)
III. IaaS (Infrastructure as a Service)

12. Service Models

13. SaaS
 SaaS( Software as a Service) is a way of delivering services and
applications over the Internet.
 SaaS provides a complete software solution which you purchase on
a pay-as-you-go basis from a cloud service provider.
 The SaaS applications are sometimes called Web-based software,
on-demand software or hosted software.
Advantage Of SaaS:
I. Cost Effective
II. Reduced Time
III. Automatic updates

14. PaaS
 PaaS (Platform as service) is the category of cloud
computing that provides a platform and environment to
allow developers to build applications and services over
the internet.
 PaaS services are hosted in the cloud and accessed by
users simply via their web browser.
Advantage Of PaaS:
I. Simple and convenient for users
II. Cost effective
III. Efficiency

15. Iaas
 IaaS (Infrastructure as service) is the basic layer in cloud
computing Service model.
 IaaS is a form of cloud computing that provides virtualized
computing resources over the internet.
 IaaS is a way of delivering services and applications over
the Internet.
Advantages of IaaS :
I. Cost Effective
II. Security
III. Maintainance

17. Advantage Of Cloud Computing
 Lower computer costs
 Improved performance
 Reduced software cost
 Universal document access
 Latest version availability
 Easier group collaboration

18. Disadvantage Of Cloud Computing
 Requires a constant network connection
 Does not work well with low – speed connections
 Features might be limited
 Can be slow
 Stored data can be lost
 Stored data might be not secured
